issue regarding 3d tessellations.

[anujyadav0693]

respected sir,
I am using this software only to generate the geometry of the microstructure and import geometry in Ansys software. I am able to import 2d geometry but I am not able to import 3d geometry. I got this type of error in Ansys.
error####

*** NOTE *** CP = 23.156 TIME= 11:47:30
A trimmed analytic surface is not possible because the group of lines
beginning with 436, 432, 426, and 437, does not lie on a common
coordinate value in the currently active coordinate system (CSYS).

*** ERROR *** CP = 23.156 TIME= 11:47:30
A non-planar area (Coons patch) is not possible because there are more
than 4 lines.

to resolve this error I think I will have to make planar areas. to make planar areas in neper I am using this code still i am getting the same error.

neper -T -n 11864 -dim 3 -domain "cube(0.05,0.004,0.004)" -reg 0 -fmax 0 -ori uniform -crysym cubic -oridescriptor euler-bunge -format tess,geo,ori

please find the error in the code and update it if possible.
I have also tried with -reg 1 and -fmax 5 nothing is not working.
thank you.

It seems that -reg 0 should have solved the problem. I cannot help more, as I'm not used to Ansys.
